Before a fruit tree can bear fruit, the flowers must be pollinated. The fertilization of fruit trees takes place differently depending on the variety.
Ornamental apples
Ornamental apples have pollen that is suitable for pollinating different apple varieties. However, if you pay more attention to the fruit as a decoration for ornamental apples, you should bear in mind that noble varieties are often not accepted as pollen donors for ornamental plants.
Blood plum and sloe
The blood plum and sloe both bloom earlier than other plum and damson varieties, but these are self-fertile and therefore not different from the other species dependent upon fertilization.
Large greengage vine
The large greengage vine needs a pollinator tree and flowers together with the house plum.
Ornamental cherry
Ornamental cherries bloom too early and, in addition, the pollination conditions for sweet cherries are so complicated that information has to be obtained from the fruit tree nursery in order to find the right one To be able to combine varieties for pollination .
Ornamental plants often have double flowers and here the stamens and stigmas are shaped as petals. Thus, these trees are not suitable as pollinators for noble varieties.
Self-fertile fruits
Self-fertile fruits include peaches and apricots, quinces, medlars, gooseberries and currants, blackberries and raspberries, walnuts and vines.
Even infertile varieties are pears and apples as well as hazelnuts and sweet cherries. Sour cherries and plums depend on the type of pollination.
